Abstract: An aircraft weapon delivery system includes in combination with the usual computer for solving fire control equations and a display generator displaying a firing pipper, further circuitry for generating a reticle for viewing on the display such that command signals from the computer responsive to movement of the aircraft control stick are passed directly to the display to move the reticle without lag time to a registering position with a target viewed by the pilot. By providing the generated reticle in the form of a circle together with manual controls operable by the pilot for passing a variable reticle signal for varying the diameter of the circle, the pilot can adjust the circle size to match the visual target, the reticle signal then constituting a function of the range of the target and the rate that the pilot must vary the reticle signal to maintain a matching with the visual target constituting a function of the rate of change of range.
